Come on, people. I know you're out there.
well one more thing on MotAO...
i like to combine it with the draconic heritage substitution levels, since you have to select arcane preparation. and well, if you think about it, there is actually nothing stopping you from casting any spell as a cooperative spell. this makes the spell a full-round action to cast, and most people select invisible spell mostly for this reason. so the entry feats, while not exactly good, are not as worthless as often pictured.
for me MotAO is just too good to pass up. 4 levels is a must for me. and i personally find it hard to not get to level 7 because i love to cast spells like control weather, statue, etc., which you won't ever select as a known spell as a sorcerer. in terms of outside of combat fun there is just no reason not to go MotAO... the only reason for not entering this prestige class would be that there is a wizard in the party. in this case i'd probably build a mailman type.
